Study On Pig Breeding Model Based On Circular Economy

Large-scale pig breeding mode development results in serious separation between breeding and planting industry under constraints of land circulation system. For profit maximization, the farm households may use excessive veterinary drugs and additives in the breeding process, which leads to the difficulties of returning the manure which contains substantial and harmful residues to the soil. Under this background, this paper studies pig breeding model from the perspective of circular economy, which has both significant theoretic and practical value.Through building the theoretical basis and research framework, this paper conduct field investigation in Beijing and takes the combination of qualitative and quantitative method to discuss how to smoothly run the circulating breeding mode. The research includes the following contents:first, this paper summarizes the development trend and problems of pig breeding; second, based on the circular economy, this paper analyses the adoption behavior and influencing factors of breeding technique from the principle of reduction, reuse and recycling; third, according to the logic of "from the source to the end", this paper defines reduction, reuse, recycling technology together as circular economy breeding mode, uses the theory of planned behavior to analyze farm households’ willingness to choose; fourth, this paper studies the cooperation degree between pig breeding industry and related industries and its influencing factors; fifth, based on public goods and externality theory, it analysis the role of government in circulating breeding cultivation mode; finally, this paper puts forward policy suggestions on circulating breeding mode from the perspective of pig farm households, related industry and government.The main conclusions of this paper are:first, according to its theoretical basis it builds the logical framework of analyzing circulating breeding mode’s operation from technological supporting, industry linkage and perfect system; second, according to the analysis of technology, the pig farm households unevenly apply circulating breeding technology unevenly, and the adoption of large-scale breeding technology is obviously higher than natural breeding, which results from maximizing profit. Third, the willingness of choosing circulating breeding mode is influenced by many factors. The awareness of feed additives affect the choosing willingness negatively, yet the knowledge of more profit, famer’s economic condition and government subsidies enhance the ratio of willingness. The paper also reveals the fact that the education is positively correlated with willingness. Fourth, the stable cooperation between pig breeding industry and related industries guarantees is the guarantee to run circulating economy breeding mode smoothly. The cooperation of pig breeding industry extending chain, waste disposal industry and circulating breeding area decides the effects; fifth, the government policy and institutional assurance are the driving forces for the application of circulating economy breeding mode. Administrative measures play an important role on rationalizing industry strategy and standardizing famers’ behavior, subsidies also stimulate the adoption of breeding technology, and the government guides the public to supervise as well.Characteristics and innovation of this study includes:based on three principles of circular economy, this paper embodies the circulating breeding technology mode and avoids the empty generalization of circulation economic research by summarizing pigs breeding technology before, during or after delivery and comprehensive introducing of circulating process which contains farm planning and construction, production inputs, breeding process control and postpartum waste management. Furthermore, focusing on the pig farm households, this paper study particularly the needed technical support, related industries’cooperation and government support, and comes up with the conditions of circulating breeding mode comprehensively and systematically...
